Hi,

I want to manipulate the data with modbus monitoring.

Here is my json

{
  "selection":{
        "FC3_key_erasing_information":{
            "address": 7,
            "quantity": 1,
            "type": "holding",
            "display": false
      }
    },
  "virtualcurve":{
    "FC3_key_erasing_information":{
      "aggregation": "avg",
      "pattern": "FC3_key_erasing_information",
      "critical": "0",
      "formatting": {
        "printf_msg": "key_erasing sensor is %.f",
        "printf_var": "$self->{result_values}->{instance}, $self->{result_values}->{value}"
      }
  }
}
}
 

With my simulator i’ve set the value to 1 but here is the result:

-bash-4.2$ /usr/lib/centreon/plugins/centreon_protocol_modbus.pl --plugin=apps::protocols::modbus::plugin --mode=numeric-value --tcp-host=X.X.X.X --config=/usr/lib/centreon/plugins/intrusion.json  --verbose
Argument "FC3_key_erasing_information" isn't numeric in sprintf at /usr/lib/centreon/plugins/centreon_protocol_modbus.pl line 100.
OK: key_erasing sensor is 0 | 'FC3_key_erasing_information'=1;;0:1;;
key_erasing sensor is 0
 

Why i get this sprintf message and also, why the value returned is 0 while the value is 1?
